Nike Vaporfly

Nike Vaporfly is the carbon-plate racing shoe family discussed in E241｜跑鞋技术迭代史：马拉松跑进2小时，靠人还是靠鞋？ as the product that reset marathon-shoe competition before Adidas Adios Pro Evo 3. The source emphasizes that the breakthrough came from combining a plate with super foam, not from the plate alone.

Key Claims

• The “4%” idea is presented as a lab running-economy claim whose real effect varies by runner weight, posture, cadence, and usage.
• The source says competitor complaints helped push governing-body restrictions around racing-shoe geometry and stack-height style advantages.
• Vaporfly and Alphafly created a consumer halo where even runners far from elite marathon pace bought top-tier racing shoes.

Connections

• Nike — parent brand.
• Carbon Plate Racing Shoes, Supercritical Foam Midsole, and Running Shoe Technology — technical context.
• Eliud Kipchoge and Kelvin Kiptum — elite runner context in the source.
• Adidas Adios Pro Evo 3 — later competitive benchmark in the episode.
